SOUTHFIELD, Mich., Nov. 15, 2016 (GLOBE NEWSWIRE) -- Federal-Mogul Powertrain, a division of Federal-Mogul Holdings Corporation (NASDAQ:FDML) has developed a new spark plug for gasoline, high BMEP (Brake Mean Effective Pressure) stationary engines. A combination of optimum materials, unique ground electrode geometry and maximum electrode surface area gives the new 'cold' plug enhanced thermal characteristics. This results in improved electrode durability and increased service life compared with other technologies available in the market.
With an industry-leading spark surface area, Federal-Mogul Powertrain's 'cold' plug reduces ground electrode temperatures by more than 200°C and provides up to four times the service life compared with standard iridium J-gap spark plugs. Specialized nickel, iridium and rhodium alloys, combined with the electrode geometry and surface area, provide the required durability when used in pre-chamber gaseous fuelled engines operating in excess of 23 bar BMEP. "Reducing electrode thermal loading, minimizing spark erosion and chemical corrosion at the gap and reducing the incidence of key failure modes such as weld joint fracture of electrodes, present the biggest challenges for spark plug technology in high output engines," explained Gian Maria Olivetti, Chief Technology Officer, Federal-Mogul Powertrain. "By developing a true dual electrode iridium design with a short 'cold' projection and annular gap configuration, we have met the latest pressure and temperature challenges, providing significant benefits over J-plug designs."
